Title: Improved apparatus for generating the relative axial movements required between a cutting tool and a round tube which is being cut to fit at an angle against the wall ofanother round tube
IPC: B23K7/00
Filed: 1963-02-04
Abstract: 1,017,254. Cutting by fusion. H. R. MORGAN. April 29, 1964 [Feb. 4, 1963], No. 4473/63. Heading B3V. Apparatus for generating the profile of the end of a tube 32 to enable it to be joined to a main tube, comprises a crank-shaft 1 rotatable and slidable axially in bearings 7, 8 and whose crank-arm 2 is interconnected by a universal joint 3, 4 with an arm 5 of an armshaft 6 also rotatable and slidable axially in bearings 9, 10, the two shafts 1, 6 being disposed at an angle corresponding to that of the tube joint, whereby upon their rotation the crankshaft 1 is caused to move axially which movement is transmitted into a relative movement between the cutting tool and tube or between the cutting tool and a cam, which cam is thus profiled in accordance with this movement. The tool is preferably a flame-cutting torch which may be swivelled during cutting to produce a bevelled edge. The crank-shaft 1 is rotated through worm-gearing 24, 25, sleeve 21 and crank-pin 19; sleeve 21 also drives through sprockets 26, 28 and chain 27, a chuck 29 carrying the tube 32. Torch 35 is mounted on a longitudinally slidable spring- loaded bar 12 connected by link 13 with the crank-shaft. The ball and socket joint 3, 4 is held in engagement by a spring 11A. The crank pin radius is adjustable to suit the radius of the tube 32 and the effective length of arm 5 is adjustable to suit the radius of the main tube; alternatively the crank arm 2 may have two sockets placed at different radii for use with an arm 5 having two ball ends spaced at different effective radii, Fig. 5 (not shown). The arm-shaft bearings 9, 10 are mounted on a bed 16 pivoted at 16A to the main bed plate 17. When the two tubes are to be offset axially, the beds 16, 17 are disposed in spaced parallel planes. In another embodiment, Fig. 7 (not shown), the torch 35 is used to cut a profile on a cam 45 which is used subsequently in another apparatus for controlling the longitudinal movment of a torch during profiling of a tube end. The two shafts 1, 6 are interconnected by a Hooke's joint 4A. Gearing and levers may be used to increase or reduce the movement of the cutting tool.

Title: Improvements in thermionic cathodes for electric discharge tubes
IPC: H01J1/20
Filed: 1930-02-11
Abstract: 348,679. Thermionic cathodes. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London, and DAVIES, L. J., 147, Murray Road, Rugby. Feb. 11, 1930, No. 4607. [Class 39 (i).] An equipotential cathode for mercury-vapour discharge tubes &c. comprises a relatively thinwalled hollow open-ended box of conducting material, embedded in the walls of which and insulated therefrom a heating element is situated so as to obtain an electron emission from both the inside and the outside of the box. In one example, the cathode consists of two concentric metallic cylinders which are coated with electronemitting material. The heater is located in, and fills the annular space between the cylinders, and consists of a helically-wound tungsten or molybdenum strip or wire which is coated, e.g. by dipping or by spraying, with a refractory material, such as kaolin, and is then heated to form a rigid structure. In a modification, the heater wire is wound on a quartz or porcelain tube, which is subsequently coated with a plastic insulating material rendered hard by baking, and is then assembled within the concentric cylinders, or is coated with a metal to form the cathode. The electron emission may be increased by the provision inside the inner cylinder of vanes or washers. The vanes radiate symmetrically from the inner cylinder and may be welded to the cylinder or may be arranged on a structure which is suitably attached thereto. The washers are arranged at right-angles to the axis of the cylinder and are spaced 2-5 mm. apart'; central holes of about 5 mm. diameter therein allow electrons to flow from the interior. Heat radiation from the cathode is minimized by one or more polished metal shields as described in Specification 309,447, [Class 39 (i), Electric lamps, Arc &c.].

Title: Method of reclassifying particulate mixed ion exchange resin
IPC: B03B5/62
Filed: 1973-01-30
Abstract: 1383734 Wet separation of particular materials CRANE CO 30 Jan 1973 4648/73 Heading B2H Particulate mixed, e.g. spent, ion exchange resins are reclassified into separate cation and anion exchange resin fractions by introducing the mixed resins into the top of a vertical column of liquid in which the cation and anion exchange resins settle at different rates of. fall, thereby separating into distinct fractions which are separately collected, the reclassification being enhanced by maintaining a laminar downward flow of liquid in the vertical column. The laminar flow of liquid operates to streamline the particulate resin flow and limits random vertical movement of the particles resulting in a reduction in the total number of particle collisions. Moreover the downward flow of liquid enhances the settling of the larger as compared with that of the smaller particles: The liquid used is preferably water and the laminar flow has a Reynolds number of between 200 and 2200. A resin-receiving vessel is preferably provided above, and adapted to communicate with, the vertical redassification column and an upward current of liquid is set up in this vessel to effect backwash of the resins to remove the fines and/or preliminary redassification of the resins prior to their passing from the vessel into the column. Reclassification may also be enhanced by increasing the buoyancy of one of the types of resins in the vertical column by maintaining a dispersion of air bubbles in the liquid therein and contacting the particulate resin with a hydrophobic, aerophilic flotation agent which selectively adheres the cation or anion resin to the air bubbles. Flotation agents specific to anion exchange resins may include a polyamine alkyl sulphate, xanthate, dithiophosphate, dithiocarbamate or an arenesulphonate. Flotation agents specific to cation exchange resins may include a polyacrylamide, primary amine, quaternary amonium salt, primary ammonium, alkyl-pyridinium salt or a thiocarbanilide. A suitable plant is described.

Title: Improvements in resilient mountings
IPC: F16F1/46
Filed: 1939-02-13
Abstract: 510,075. Resilient supports. UNITED STATES RUBBER CO. Feb. 13, 1939, No. 4707. Convention date, Feb. 16, 1938. [Class 108 (iii)] A resilient support of rubber or a rubber substitute 1, Fig. 2, for a vibrating body 4 is stretched a distance B under static load in excess of 75 per cent. of its normal length and the oscillating range C of the body is at least in part beyond its loaded length. It is stated in the Specification that rubber under tension has a lower fatigue life when the rubber is subjected to slight degrees of extension, when compared with substantially higher degrees of elongation of the rubber body. This characteristic is shown in Fig. 3 where the abscissae represent percentage, values of elongation of the rubber body with reference to its original length and the ordinates represent percentage values with reference to the original length of the range of oscillations in excess of the elongation produced by the static load. Each curved line on the graph represents the fatigue life of a conventional rubber stock utilized for tension mountings under a definite number of elongation cycles but under different conditions of elongation. Thus, for example, the point X on the graph represents an extension of 200 per cent. static load and 200 per cent. oscillation range the fatigue life of the rubber being ten million cycles. For an extension of 75 per cent. or 300 per cent. of the static load points A and B and with the same oscillation range the fatigue life is reduced to one million cycles. The crosssectional area of the rubber may be reduced to suit the elongation for a given load and the characteristics of the rubber may be changed to bring it within the desirable limitations of elongation. The rubber used has a durometer hardness of 30-50. Various compositions of the rubber used are shown in the Specification.

Convention date, Feb. 15, 1935. [Class 108 (iii)] A shock-absorbing suspension device for motor vehicles and cycles, aircraft, &c. comprises a cylinder partly filled with liquid, a main piston 21 bearing on the liquid and adapted to restrict flow of liquid therethrough, and an annular piston 4 slidable on the piston-rod 2 and pressed towards the main piston by a spring 10. As shown the annular piston 4 separates the spring 10 and a volume 12 of compressed air. In operation, on compression of the device, liquid is forced through apertures 3 on the piston 21 and, owing to the decreasing volume of the cylinder 1 due to the entrance of the piston-rod 2, the air is compressed and forces the annular piston 4 to move against the action of the spring 10. Additional resistance is provided by an outer spring 7. In a modification the air-chamber 12 and spring 7 are omitted. The Specification as open to inspection under Sect. 91 comprises also a construction on which a throttled external byepass extends from the liquid space below the piston 2<1> to the space above the annular piston, and a further construction in which an auxiliary, spring-pressed piston is slidable in the piston-rod. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specifications 315,068, [Class 108 (iii)], and 405,835.

Title: Logic circuit
IPC: H03K3/33
Filed: 1963-02-08
Abstract: 1,032,422. Semi-conductor logic circuits. SPERRY RAND CORPORATION. Feb. 8, 1963 [Feb. 21, 1962], No. 5137/63. Heading H3T. In a logic circuit comprising a tunnel diode which may be switched to its high voltage state by the coincident application of a clock pulse and an input signal, the input is connected to the tunnel diode by a semi-conductor charge storage device. As described, the charge storage device is a " recombination diode," the current/time characteristic of which is given in Fig. 1 (not shown). When the anode of such a device is switched from a positive to a negative potential, a large reverse current flows initially due to charge storage and the device may be used to provide amplification. In the embodiment of Fig. 3 application of a high level input to at least one of the diodes 302 reverse biased the recombination diode 312, presenting a high impedance to a set clock pulse from source 306, so that it does not switch the tunnel diode 320 to its high voltage condition. If all inputs to diodes 302 are at a low level, the diode 312 is forward biased, forward current flowing through it from source 316 to source 310, and application of a set pulse from source 306 reverse biases the diode, producing the reverse current pulse referred to in connection with Fig. 1. The pulse is sufficient to switch the tunnel diode 320 to its high voltage state. The diode 320 is then subsequently reset by the reset clock source 322. In a second embodiment, Fig. 5, switching of the diode is effected by the collapse of the field in inductor 550 at the termination of the reverse current pulse. A number of stages of the type shown in Figs. 3, 5, may be cascaded, Fig. 7 (not shown). In a further modification of Fig. 3, Fig. 9 (not shown) the input diode gates may be arranged in groups, each with its own recombination diode.
